   Hi there,
   
   Thanks for all your hard work on ECharts and the great documentation for it.
   
   ## Issue description
   
   When using the online builder to generate a leaner bundle containing only 
the features I am using, I noticed that switching to this bundle from the full 
uncompressed bundle broke the ARIA description.
   
   I wondered if this was related to the features I had removed, so for 
experiment's sake I tried building an Echarts file with every chart, coordinate 
system, and component, which I would expect to be functionally identical to the 
full, uncompressed 
[echarts.js](https://github.com/apache/echarts/blob/5.6.0/dist/echarts.js) 
distribution, but this still didn't generate ARIA descriptions, and the bundle 
generated file was about ~300KB smaller than the full distribution.
   
   ## Reproduction
   
   I have created a minimal test case showing this behaviour in action.
   
[Here](https://jegtnes.github.io/echarts-aria-bundle-reproduction/failure.html) 
is an HTML document rendering a chart with the builder bundle, not outputting 
an aria-label.
   
[Here](https://jegtnes.github.io/echarts-aria-bundle-reproduction/success.html) 
is an HTML document rendering a chart with the full bundle, successfully 
outputting an aria-label.
   
   ## Expected outcome
   Generating an Echarts file from the online builder that includes the 
functionality to successfully output an aria-label from a chart.
   
   ## Actual outcome
   Generating an Echarts file from the online builder does not include the 
functionality to successfully output an aria-label from a chart.
   
   Let me know if you need any more information or if I can help to address 
this issue in any way. Many thanks!
